Jonathan of Quebec is specialized in scientific glass making. To create these gorgeous heart earrings he fuses art and science together. His practice involves a modern form of alchemy, turning silver and gold to smoke at temperatures above 2000 degrees fahrenheit. Borosilicate is generally used for scientific purposes but Jonathan found it can serve as a rich medium for artistic jewelry designs; as he captures smoke through this process, to create majestic patterns. Each pair of heart earrings measures .5 inches in diameter, and stainless steel posts. Handcrafted for Uno Alla Volta, from the heart and hands of the artisan.
